With EnableColorTiling enabled, when I run certain programs, my X server becomes completely distorted, with screen elements rendering correctly, but in mis-positioned blocks all over the screen. X remains responsive, but I cannot return it to a usable state from the 'bugging' condition. There is no output in dmesg or Xorg.0.log relevant to this. Setup: Distro: Gentoo Kernels: linux-2.6.36, linux-2.6.37, linux-2.6.38-rc5 Driver : x11-drivers/xf86-video-ati-6.14.0 DDX : r600 (another user in #gentoo had this with r300) Mesa : media-libs/mesa-7.10 (gallium and classic) LibDRM: x11-libs/libdrm-2.4.23 X-Server: x11-base/xorg-server-1.9.4 KMS : Enabled EnablePageFlip : Enabled, Disabled EnableColorTiling: Enabled I originally encountered this bug with the 'classic' mesa renderer(?), but it affects 'gallium' also. Reproduction: EnableColorTiling >> /etc/X11/xorg.conf Start X Run Openoffice (Or some in-browser java applets, or Gogglesmm, or some elements of calibre) Hardware: 01:00.0 VGA compatible controller: ATI Technologies Inc RV770 [Radeon HD 4850]
Created attachment 43590 [details] Xorg.0.log Xorg.0.log for completeness -- there is no error or warning info.
